American voters give a slight edge to President Barack Obama over Congressional Republicans when it comes issues related to health care, according to a new poll released Tuesday.

The latest poll from Democratic-leaning Public Policy Polling (PPP), conducted on behalf of Daily Kos and SEIU, shows that 47 percent of respondents trust Obama on health care issues that are important to their families. Conversely, 43 percent trust members of the GOP in Congress over the president.

With the Supreme Court expected to rule Thursday on the health care overhaul passed by Congressional Democrats and signed into law by Obama in 2010, the issue could ultimately be revisited on Capitol Hill — particularly if the high court strikes down part or all of the law. Tuesday's poll also showed Obama with a 3-point lead over presumptive Republican nominee Mitt Romney, 48 percent to 45 percent.
